register_optics: Register Seriation Based on OPTICS

Description

Use ordering points to identify the clustering structure (OPTICS) for seriate().

Usage

register_optics()

Value

Nothing.

Details

Registers the method "optics" for seriate(). This method applies the OPTICS ordering algorithm to create an ordering.
